thank you jlufer, I just remember seeing some statistics from somewhere on steemit at the time I joined. And there are daily statistics posted of number of users , active users etc from a variety of people @masteryoda does a fantastic daily update. You can also goto https://steemd.com/distribution and see the total number of accounts. Unfortunately I don't know if there are any stats on users in Argentina!
